test_strcpy(), test_strncpy() and test_stpcpy() applied the same offset to the source and to the destination, so both pointers always shared the same word congruence. Architecture optimized copy routines take a different code path when the two offsets differ: a byte prologue to align the destination, then either a byte fallback or a shift-merge loop that recombines two source words per store. None of that was reached by the test. Vary the source and destination offsets independently over 0..7 in those three tests, so both the equal congruence (aligned word copy) and the unequal congruence (shift-merge) paths are covered, and report both offsets on failure so a regression points at the offending combination. Also drop the ARCH_TOOLCHAIN_GNU dependency from TESTING_ARCH_LIBC. The test only uses standard C string functions and perf_gettime(), with no GNU specific construct, so it builds with non GNU toolchains such as TASKING as well. Impact: test only, selected by CONFIG_TESTING_ARCH_LIBC (default n). Dropping the ARCH_TOOLCHAIN_GNU dependency only widens the set of toolchains that may select the test, no existing configuration changes. Testing: built and ran sim:nsh on Linux x86_64 (Ubuntu 24.04, gcc 13.3.0) with CONFIG_TESTING_ARCH_LIBC=y. strcpy, strncpy and stpcpy report PASSED for all 64 offset combinations, and "arch_libc_test Passed".
